PERIODIC REACTOR PLANT LEAK RATE TEST. CORE I, SEED 2. TEST RESULTS T- 641102

Technical Report ·
OSTI ID:4073757
The cooling system leakags in the Shippingport PWR was measured before and after removal of the relief valve leakags cooler. The relief valve leak rate increased and data became more consistent after cooler removal, indicating that the cooler restricted relief leakags flow. The collection vessel was pressurized with nitrogen for the purpose of breaking a possible vacuum in the relief valve dischargs line; the pressurizing had no effect. (T.F.H.)
